Interwoven sandwich panel structures and related method thereof

Abstract

An interwoven sandwich panel structure made for high intensity impulse mitigation comprises a top and bottom face panel integrally interwoven to a core by creating a preform from the interweaving of cross-wise and length-wise threads and then infusing it with a thermoset polymer resin such that it requires no stitching, bonding, or fastening to attach core to the face panels removing the primary weak points of a sandwich panel structure.
